A d20 CT scan

I had to come up with a sample for a CT scan experiment in a physics laboratory, and I chose to scan this d20. The scan took ~19 hours and produced ~10 GB of data across 1800 slice reconstructions.

The gif presents every 10th image. The numbers are carved and painted with some metallic-looking paint, which is pretty much confirmed by the attenuation seen in the pictures. I was very happy with the results since the plastic materials with different colors can be distinguished.
There are also some air bubbles and I'm working to find out the center of mass.
The numbers on each face are pretty much random oriented, but here's the order:
(clockwise, one z-level per row, topmost first)
3 / 17 / 7 / 1 / 19
16 / 10 / 15 / 13 / 9. quickly followed by
6. / 8 / 12 / 5 / 11
14/ 20 / 2 / 18 / 4
